Really wanted to buy a Winnie Sprinter View a couple of years ago.  Here is a suggestion.  Goggle and go to the MB Sprinter site for the USA.  Take a look at where the dealers/service centers are located.  See if you are comfortable in a rural area with an authorized service center at that distance.   That is what stopped me from buying one.  
Oklahoma City has a huge Freightliner center.  Next stop west was Albuquerque back when I looked.  From ABQ, next north was Denver.  And so on.  The folks like FEDEX and UPS have their own mechanics and full service centers for their fleets.  I didn't want to be in line at Freightliner.   There are some independent guys within ten miles of my house that will work on them, but I was buying a new rig and so needed a warranty center, not one of these folks.  
If I traveled in a more densely populated area of the country most of the time like many on this forum seem to enjoy, I would buy one.  I wrestled with this for a couple of months and bought a C on a Ford chassis.  I don't think there is a county seat town in the country that doesn't have a Ford or Chevy place.
